Yuko, When Will You Create Star Breathing

"Huh? You're all still alive?" the demon slowly approached. "You're not even injured."

"I'll definitely become stronger if I eat you."

"Careful not to break your teeth," Yuko spat out a mouthful of blood and gripped her katana.

Kokushibo suppressed the blood welling up in his throat and leaned on his sword, trying to stand.

The demon licked his lips. "I've decided. I'll start by eating your legs, so you can personally experience the reality of being eaten."

Yuko felt a wave of nausea and said dismissively, "Foot fetishist? Are you a pervert?"

Yuko tried her best to regulate her emotions, slowing the fear in her heart.

She had thought that as a transmigrator, she wouldn't be afraid of creatures she had seen countless times in anime. But when the hideous, humanoid form truly appeared before her, Yuko felt a deep discomfort and fear from the bottom of her heart.

The demon's forehead veins bulged. He didn't quite understand, but he was furious.

When the demon attacked with inhuman speed, Yuko had only one thought left in her mind.

Damn it!

If only she had known, she would have definitely changed position mid-air and put Kokushibo in front.

Suddenly, a wisp of clear breeze seemed to blow, scattering the dark clouds and ruffling a strand of Yuko's hair.

Beneath the full moon, a crimson figure descended from the sky.

Holding a blade that blazed under the full moon, a god-like posture entered their vision.

The demon's head had already flown off without a sound, and its body lying before them was rapidly dissolving.

Neither of them saw his movements clearly.

Tsugikuni Yoriichi reappeared before them after more than a decade.

Yuko let out a sigh of relief and waved happily at him. "Yoriichi~ Long time no see."

Even though they hadn't seen each other for ten years, the three of them looked almost identical.

Especially the twins Kokushibo and Yoriichi, apart from the markings on their faces, there was no other way to distinguish them.

Kokushibo's face had gained some softness and calmness, like Yoriichi's.

Yoriichi's face, with a bit more charm and softness, was Yuko's face.

The only significant difference between the three was their height.

Yuko, at only 1.7 meters, was nearly twenty centimeters shorter than her two elder brothers, while Kokushibo stood at a towering 1.9 meters.

Even Yuko's height was considerable for this era, let alone the Tsugikuni brothers; they were like little giants when standing in a crowd.

Yoriichi smiled faintly at her and knelt before his elder brother, Kokushibo.

"I'm sorry, Elder Brother, I'm late."

Yoriichi felt apologetic for not being able to save his brother's subordinates.

Kokushibo simply leaned against the tree trunk, watching his brother. The flame of jealousy, almost forgotten deep within his heart, flared up again in his pupils.

After so many years, the gap between them had grown even wider.

While he had been smug about becoming a samurai, Yoriichi was already capable of easily beheading demons.

Through Yoriichi's words, they learned of the existence of demons in this world.

Both of them had sustained injuries of varying degrees.

After Yoriichi briefly bandaged them, he took them to the Demon Slayer Corps' residence for treatment.

Kokushibo spoke very little throughout the process, while Yuko occasionally chatted with Yoriichi.

Yuko remarked, "Your communication skills have improved a lot compared to before."

Yoriichi smiled gently. "Yuko, you haven't changed at all. Still as lively as ever."

Yuko patted his shoulder. "I'll take that as a compliment."

Yoriichi brought the two of them to the Demon Slayer Corps to settle them in. The Demon Slayer Corps during this period was not as secretive as it would be in later generations.

Lying in the hospital bed, Yuko began to daydream.

If nothing unexpected happened, the plot should be unfolding as expected.

She hadn't watched much of Demon Slayer, only finishing the first season, plus some popular content she occasionally saw online.

In reality, her understanding of the overall plot of Demon Slayer was fragmented and incomplete.

She was the type who, upon joining a Demon Slayer chat group, would be questioned and kicked out within three sentences.

However, if nothing unexpected happened, Kokushibo would soon join the Demon Slayer Corps and have no time for family matters, allowing her to take the opportunity to join as well.

Then she could learn the Sun Moon Breathing Style from her two elder brothers, embark on the path to the pinnacle of life, and become Muzan's new daddy.

She felt a little excited just thinking about it.

As for how the Tsugikuni family would fare without its head...

Yuko could only say that she could barely protect herself and had no time to worry about others.

The house hadn't offered much warmth since Akino's passing and Yoriichi's departure.

As expected, after recovering from his injuries, Kokushibo told Yoriichi of his desire to join the Demon Slayer Corps.

Taking the opportunity, Yuko raised her hand and seconded, "I want to join the Demon Slayer Corps too."

Kokushibo glanced at her indifferently, making Yuko feel restless.

If Kokushibo disagreed, wouldn't Yoriichi, his younger brother, have to obey him?

Fortunately, he eventually withdrew his gaze and said nothing more.

Yuko breathed a sigh of relief, finally able to avoid marriage.

Yoriichi didn't understand the family situation and simply saw this as support from his brother and sister.

He became the recommender for the two to join the Demon Slayer Corps.

Thus, Yuko's sixteen years of life since transmigrating finally began to move in the right direction.

It was only after joining the Demon Slayer Corps that Kokushibo learned from others about his younger brother's power.

Before Yoriichi's arrival, the swordsmen of the Demon Slayer Corps were essentially fighting demons with Nichirin Blades, relying solely on their own sword skills, and the death rate was terrifyingly high.

After Yoriichi's arrival, he not only created the Origin Breathing Style—Sun Breathing.

But because others couldn't master it, he also taught them to create breathing styles suitable for them, namely the five major breathing styles: Rock, Lightning, Wind, Water, and Flame.

This increased the efficiency of demon slaying and greatly reduced the casualty rate of the Demon Slayer Corps.

It could be said that Yoriichi's arrival pointed the way for the future of the Demon Slayer Corps.

Yoriichi was never stingy with teaching breathing styles.

As elder brother and sister, the two received his personal guidance.

The two stood in an open space, holding practice Katanas, their eyes closed.

"Hiss~"

Orange-red breath escaped Kokushibo's lips.

Suddenly, his calm expression froze, his lungs burned unbearably, and he coughed repeatedly.

He couldn't use Sun Breathing.

On the other side, Yuko endured the burning sensation in her lungs and forcibly ran Sun Breathing.

Just as Yoriichi's gaze noticed the condition of her lungs and was about to interrupt her, Yuko's eyes snapped open.

"I learned it!"

Kokushibo, who had just been overwhelmed by a sense of loss, felt like he had fallen into an ice cellar. He quickly turned his head to look.

"..."

Blood flowed from Yuko's nose and mouth.

Seeing her two elder brothers looking at her, Yuko winked playfully at them. She was about to demonstrate Sun Breathing: First Form: Circular Dance, and then... Yuko, who mistakenly thought that enduring the burning sensation meant success, her vision went black.

Literally, her vision went black.

After a long while, Yuko, who had been rescued, sighed, "I thought I had learned it."

Kokushibo: "..."

Yoriichi maintained his calm smile, "It's okay, finding the breathing style that suits you best is the most important thing."

"Sun Breathing isn't necessarily stronger than other breathing styles."

Yuko smiled outwardly, but inwardly she grumbled.

Who are you kidding!

She had seen the plot; Tanjiro using Dance of the Fire God almost defeated a Lower Rank demon!

Days passed as they learned breathing styles.

Kokushibo lacked the talent for Sun Breathing, but he was not without talent.

Relying on Sun Breathing, he quickly created his own breathing style, which was also called Origin Breathing Style by later generations—Moon Breathing.

"Um... Elder Brother, can you teach me?" Yuko forced a smile, her voice sweet, and she asked him to teach her, steeling herself.

Kokushibo's lips curved slightly, "Why is the address correct at this time?"

Yuko's face was covered in black lines, and her sweet voice instantly retreated, "Forget it if you're not teaching me!"

I'll create my own Star Breathing!

Ever since Kokushibo created Moon Breathing, not only did she jokingly say she would create Star Breathing, but even the onlookers within the Demon Slayer Corps were calling out.

"Yuko, when are you going to create Star Breathing?"

Yuko always replied like this.

"Today!"

However, her understanding of breathing styles was insufficient. Just following along with the learning exhausted her brain, let alone creating one herself.

Otherwise, she wouldn't have come crawling to Kokushibo to learn Moon Breathing.
